Your electrical panel is the heart of your home’s electrical system.

If it’s outdated or undersized, it can struggle to keep up with modern demand — leading to nuisance breaker trips, overheating, or even safety hazards.

Here’s how to tell if your panel may be too small.

⚡ What Size Panel Does a Modern Home Need?

Most modern homes require:

• 200-amp service (standard today)
• Sometimes 400 amps for large homes or high-demand properties

Older homes often have:

• 60-amp service
• 100-amp service

While that may have been enough decades ago, today’s power usage is much higher.

Standards for safe electrical systems are outlined in the National Electrical Code, which reflects today’s electrical load expectations.

🔌 Signs Your Panel May Be Too Small

1️⃣ Frequent Breaker Trips

If breakers trip regularly, your system may be overloaded.

2️⃣ Flickering Lights

Especially when large appliances start.

3️⃣ You’re Using Multiple Power Strips

This often means you don’t have enough dedicated circuits.

4️⃣ Panel Is Completely Full

No space for additional breakers = no room for upgrades.

5️⃣ You’re Adding Major Equipment

Examples:

• EV charger
• Electric water heater
• Heat pump
• Hot tub
• Finished basement

Older panels weren’t designed for these loads.

🔥 Safety Risks of an Undersized Panel

An overloaded panel can lead to:

• Overheated wiring
• Damaged breakers
• Electrical fires
• Premature appliance failure

The National Fire Protection Association reports that electrical failures remain a leading cause of residential fires.

🏠 When Should You Upgrade?

You should strongly consider a panel upgrade if:

• Your home is 30+ years old
• You still have 100-amp service
• You’re renovating
• You’re installing EV charging
• You plan to add high-powered appliances

A panel upgrade is often required before adding new major electrical loads.

💰 Is a Panel Upgrade Worth It?

Yes — especially long-term.

Benefits include:

• Increased safety
• Support for modern appliances
• Higher home value
• Better reliability
• Insurance compliance
• Future expansion capability

It’s an investment in your home’s infrastructure.

🛠 What’s Involved in a Panel Upgrade?

Typically includes:

• Permit application
• Utility coordination
• New panel installation
• New breakers
• Grounding upgrades
• Inspection approval

Local municipalities require permits and inspections to ensure compliance with safety codes.

Final Thoughts

Your electrical panel isn’t something you think about every day — but it powers everything you rely on.

If your home is older or you’re planning upgrades, it may be time to evaluate whether your panel is ready for today’s electrical demand.

An assessment now can prevent problems later.
